Specification of Letters Patent. Patnted June 30, lgl.

Application led August 5, `1913. Serial No. 783,128.

T0 all 'whom t may concern Be it known that I, VILLIs D. Rises, a citizen of the United States, residing lat Ashland, in the county of Saunders and State of Nebraska, have invented new and useful Improvements in Boring Devices, of which the following is a specification.

The invention relates to a boring device, and more particularly to the class of earthl augers.

The primary object of the invention is the provision of a device of this character wherein the sinking of casings or tubings within river beds or in the ground for constructing bridges or other superstructures will be expedited, the device being designed to collect the dirt cut so that the same can be removed from the hole by the dumping of the dirtfrorn the bucket or barrel of the said device after the same has been removed from the hole.

Another object of the invention is the pro vision of a device of this character wherein the auger or the cutter is rotated or driven in a novel manner so as to assure the proper cutting action for severing the earth strata, the loose earth being delivered into a bucket or barrel which is rotated through the medium of a gear connection and is free to slide longitudinally within a casing so that the depth of the hole can be varied as the occasion may require.

A further object of the invention is the provision of adevice of this character which is of novel form, and readily and `easily operated.

A still further object of the invention vis the provision of a device of this character which is simple in construction, reliable and efficient vin operation, and inexpensive in manufacture.`

lVith these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings :Figure 1 is a side elevation of a device constructed in accordance with the invention, the same being shown .dinal sectional view thereof.

` Y Loosely surrounding ready for use. Fig. 2 is a vertical longitubottom plan view. Fig. 4 is a sectional 'view on the line i-stof Fig. 1. Fig. 5 is a sectional view on 'the line 5 5 of Fig. 1.

-F 1g. 6 1s a sectional view o n the line GF6,

of Fig. 3. Y .y

Similar reference characters .indicate corresponding parts throughout the several views inj the drawings.

Referring to `the drawings by numeralg Fig. 3 1s a the device comprises a cylindrical casing 10 which may be of any desirable length and is formed in its bottom 11 with a central opening12 through which is adapted to work a tubular bucket or barrel 13, the lower end or .bottom of whichincludes a stationary semi-circular shaped section 14E and a swinglng semi-circular shaped section 15 forming a drop door, thepstatlonary orl permanentsection 14 being provided with an entrance slot 16,'while mounted eXteriorly of the said` section 14 parallel with one edge of the slot 16 and partly projecting thereover is a cutting blade 17 which is adapted to cut into the earth and to direct the samethrough the l being rotated in scribed. v

the bucket or barrel` slot .16 into the bucket or barrel 13 for col-i' Vlection therein, the said bucket or barrel 13 a manner presently del 13 and arranged with-in the casing 10 is a'" ring-like cog gear or wheel 1S which will be hereinafter termed the bull wheel, the salne being formed at diametrically opposite points with notches 19 in which engage,

guide angle irons 20, the same being lixed eXteriorly to therbucket or barrel 13y at diametrically opposite points thereof andare disposed. longitudinally thereof throughout the length of the same so that the saidv bucket` or barrel 13 is-free to move longitudinally lwithin the casing 10 through the opening 12 in the bottom 11 thereof'without disturbing the bull wheel 18 which when rotated will impart similar ymovement to the bucket or barrel.

Journaled within the casing 10k at'fdia" metrically opposite points of the bull wheel 1,8 arencog gearsor pinions 21 and. 22respectively, the latter pinion serving as an idler and is fixed to a stud shaft 3 suitably j ournaled within the casing, while the pinion 21 is i'iXed to a driving shaft 24- journaled in brackets or bearings 25 secured to the inner face of the casing 10, the shaft 2l being disposed longitudinally within the lat ter and has fixed to its upper or outer end a beveled gear 26, the same meshing with a beveled pinion 27' secured to a driving shaft 28 journaled in the casing 10 at right angles to the shaft 24, and this driving shaft i28 projects exteriorly of the casing and is connected in any suitable manner with a motor for rotating the same. The cog gears or pin-` ions 21 and 22 mesh with the bull wheel 18 so that thebucketor barrel 13 will be rotated within the casing 10 when the driving shaft 28 is active, the said bull wheel 1S lbeing formed with an outer peripheral iange 29 which overhangs the gears or pinions 21 and 22 `so as to sustain the said bull wheel in alineinent therewith and to prevent dis placement of the said bull wheel in one direction on the sliding of the bucket or barrel 13 longitudinally within the casing.

The inner or lower ends of the irons 20 are formed with out-turned abutment shoulders 30 which are adapted to enga-ge the bull wheel 18 when` the bucket or barrel is being lifted or removed from thecasing 10, and in this mannerthe said bull wheel is disengaged from the pinions 21 and 22 on the removal of the bucket or barrel from the casing. L

The door section 15 at a point therein is formed with a notch 31 which is arranged in the path of movement of a latch member comprising a lever 32 formed with opposed semi-circular shaped swells 33 and 311 respectively, the latter swell being of considerably less size than the swell 33 and corresponds with the size of the notch 31 in the section 15, while the swell 33 is of considerably greater size than the said notch 31, and this latch member is supported upon a pivot 35 mounted in a bearing 3.6 formed on the barrel or bucket 13 so that on the swinging of the lever 32 in one direction the swell 33 will be thrown in alinement with the notch 31 and by reason of the size of the swell the section 15 will be locked position so that the contents of the bucket or barrel can be readily dumped through the bottom thereof.

The section 15 of the bottom of the bucket or` barrel 13 is connected to the section 111 through the medium of hinges 3T, thus permitting the swinging of the said section 15 to open or closed position.

ln the use of the device the casing 10 is brought to rest by its bottom 11 contacting with the river bed or the earth surface, it being understood of course that the bucket or barrel 13, is arranged within the said cas ing and the motor connected with the driving shaft 2S is started so that the said bucket or barrel will be rotated, and during this action the blade 17 will cut into the earth or river bed, thereby severing or cutting the dirt which will be forced through the slot 16 in the bottom of the bucket or barrel 13 to be deposited within the latter. When the bucket or barrel 13 has been filled with loose dirt or partly filled to any degree the same is removed from the casing 10 and thereafterthe latch member which is normally in locking position isreleased to permit the opening of the door section 15 which permits the dumping ofthe contents of the bucket or barrel. l/Vhen the bucket or barn rel 13 is rotated and the blade 17 is cutting the earth it will form a hole wi thin the earth or river bed so as to permit the driving or sinking of a casing or tube within the said 'hole for the erection of a superstructure or bridge,
